[0025] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0026] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0028] like Figure 1-6 As shown, a torque detection tool preferably used in an embodiment of the utility model has a first direction Z, and the torque detection tool includes a connecting piece 1 and a torque wrench 2.

[0029] The connecting member 1 includes a first connecting portion 11 and a second connecting portion 12. The first connecting portion 11 has a first end 111 and a second end 112 relative to each other in a first direction Z. The first end 111 is recessed along the first direction Z to provide a connecting groove 113. The connecting groove 113 has a first center line 10. The inner side wall of the connecting groove 113 is provided with a plurality of tooth grooves 114 distributed around the first center line 10. The second connecting portion 12 is fixedly connected to the second end 112. The torque wrench 2 can be detachably mounted on the second connecting portion 12.

[0030] Based on this technical solution, the staff can insert the connecting rod 3 of the electric head into the connecting groove 113 and make the multiple connecting teeth 31 on the outer wall of the connecting rod 3 respectively engage with the multiple tooth grooves 114, so as to install the connecting piece 1 on the electric head, and then install the torque wrench 2 on the second connecting part 12. The torque wrench 2 can realize the torque detection of the electric head through the connecting piece 1. After the detection is completed, the torque wrench 2 can be removed from the second connecting part 12, and the connecting piece 1 can be removed from the connecting rod 3 of the electric head, which is convenient for the staff to carry and move; therefore, the torque detection tool provided by the utility model can install the torque wrench 2 on the electric head through the connecting piece 1, so that the torque wrench can realize the torque detection of the electric head, and the structure is simple, easy to move, and easy to use.

[0031] When the force inside the electric head is large, the force will eventually be applied to the brake device; multiple switching of the electric head will cause the brake pads to wear, and the wear of the brake pads will cause the torque of the brake device to decrease. When the electric head is in place, the required braking torque will be greater than the torque that the brake device can provide, which will cause the brake device to slip. At the same time, the slipping phenomenon will aggravate the reduction of the braking torque; the current torque test bench directly measures the output torque of the output shaft of the electric head through the torque test bench, and cannot help the staff to identify and measure whether the brake device will slip; and by using the torque detection tool provided by the utility model, after the torque detection tool is installed on the electric head, when the torque wrench 2 reaches the set torque wrench value, the staff can judge whether the brake device has slipped by the state of the torque wrench 2, that is, the torque detection tool provided by the utility model can help the staff to judge whether the brake device of the electric head has slipped under the set torque wrench value, which helps to help the staff quickly judge and find out the cause of the failure of the electric head, and helps to improve the work efficiency of the staff.

[0032] The torque detection tool provided by the utility model can be reused, and the staff can use the torque detection tool as a special tool for acceptance of the electric head and fault detection of the electric head, thereby improving work efficiency.

[0042] In this embodiment, the first direction Z is the height direction of the detected workpiece, and the first plane is a horizontal plane.

[0043] In this embodiment, the second connection portion 12 is integrally formed at the second end 112. The second connection portion 12 is connected to the first connection portion 11 by integrally forming, which has the advantages of convenient processing, high processing accuracy, and high strength.
